  • Page 11: Installation

    • The design of piping systems, anchorages and other areas of the installation is not the responsibility of VOGT S.A. • VOGT S.A. only offers the data and comments as an aid, but cannot assume responsibility for the design, assembly and operation of an installation.

  • Page 12: Anchor Bolts

    5.5 Anchor Bolts VOGT S.A. supplies the pumping equipment with bases, these must be anchored to the foundation by means of anchor bolts, as shown in figure 7 and applying the tightening torque according to table N° 4.
  • Page 13 Installation Figure 8 The diameters of the pipes, valves and fittings must be calculated according to the expected head losses in the installation and in such a way that the fluid velocities are: • Velocity in delivery pipe: 2 to 3 m/s. •...
  • Page 14 Installation The end of the suction pipe, which goes at the source of the fluid, should be submerged at least 4 times its diameter to avoid the formation of vortices, which cause air to pass into the pump and cut off the liquid flow, figure 10. After the suction and discharge pipes have been installed, they should be cleaned of any debris before starting up the equipment, in order to avoid damage to the pump and other equipment installed in the system.
  • Page 15 That is why VOGT S.A., recommends the use of expansion joints as part of the piping system that connects to the pump, when conditions warrant it, see figure 13.

  • Page 16: Before Start-Up

    Start-up 6.1 Before Start-up After a pump has been installed and all mechanical, hydraulic and electrical connections have been made, it is ready for commissioning. However, prior to initial start-up, the following is recommended: 6.2 Pump Priming CAUTION Never run a pump dry. Most centrifugal pumps have a mechanical seal or stuffing box, therefore they cannot be run dry under any working conditions, otherwise the sealing elements will be seriously damaged.
  • Page 17 Start-up 6.6 Engine Considerations CAUTION It is important to check before the first start-up that the technical specifications of the motor, which come on the nameplate, correspond to the technical characteristics required by the pump and those of the place where the motor is going to operate. Verify that: •...
  • Page 18 Start-up 6.8.1 Instructions for the Connection of Three Phase Electric Motors To make a delta connection, the bridges are placed in the electric motor box connecting: U with Z, V with X, W with Y. The wires from the electric panel to the motor junction box connect the terminals: U to U, V to V, W to W, (see fig. No. 14-a). To make the star connection connect together the three terminals: X-Y-Z of the junction box and connect the terminals U-V- W with the corresponding terminals U-V-W on the electric panel.

  • Page 19: Maintenance

    Maintenance 7.1 General Considerations CAUTION • Adequate and periodic maintenance of the equipment is essential to obtain a good level of performance and an extension of the service life. • For the motor, the required service intervals and the type of maintenance to be performed are described in the MAINTENANCE SCHEDULE described in the respective motor manual provided by the manufacturer.
